polyhydroxysterol 1 beta,3 beta,5,6 beta-tetrahydroxy-5 alpha-androstn-17-one (1) was isolated from the soft coral Sarcophyton glaucum. The structure of 1 was deduced from comparison of the spectral data with those of known 1 beta,3 beta,5 alpha,6 beta-tetrahydroxysterols and confirmed by the synthesis starting from 1 beta,3 beta-dihydroxy-5,16-pregnadien-20-one (6a).
一种新的聚羟基
甾醇 1 beta,3 beta,5,6 beta-tetrahydroxy-5 alpha-androstn-17-one (1) 从软珊瑚 Sarcophyton glaucum 中分离出来。1 的结构是从光谱数据与已知的 1 beta,3 beta,5 alpha,6 beta-tetrahydroxysterols 的光谱数据的比较中推导出来的,并通过从 1 beta,3 beta-dihydroxy-5,16-pregnadien-开始的合成得到确认20 一 (6a)。
